Extract Tea leaves in strainer, by rotating the shaft by a driving source, is obtained so as to discard by reversing the tea strainer.

[0008]

When the signal for the tea supply command is input, a predetermined amount of tea leaves are supplied into the tea strainer, and then hot water is supplied into the flow passage of the tea strainer through the hot water supply passage in the shaft. The tea leaves are brewed by the hot water, and the tea leaves are extracted and the tea liquid is extracted, and the tea liquid is poured into the cup above the cup station.

After the tea liquid is poured into the cup, the shaft is rotated by the operation of the driving source, the tea strainer is reversed, and the tea dregs inside are discarded. After that, the drive source rotates in the opposite direction, the tea strainer rotates in the normal direction and returns to the original horizontal state.

During the extraction of the tea liquor, the hot water is sprayed from the ejection holes formed in the upper part of the inner circumference of the tea strainer to the tea leaves inside the tea strainer. Tea liquor is often extracted. Further, since the ejection holes from which the hot water is ejected are arranged in the inner peripheral portion of the tea strainer, the hot water does not scatter around the outside of the tea strainer.

Further, since there is no means for spraying hot water with the shower nozzle in the tea strainer, it is not necessary to arrange the tea strainer at a particularly low position, and therefore the position of the cup station disposed below the tea strainer is not lowered. As a result, it becomes possible to easily take out the cup on the cup station.

Further, since the hollow portion of the shaft supporting the tea strainer is used as a means for guiding the hot water into the tea strainer, a separate hot water supply pipe is not required, and the structure is simple and inexpensive.
